To 0:23 whom it may concern:

' Bejit knownthat I, WILLIAM N. SPRINGER,

of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Gang- Plows and I do hereby declare the follow- 'ing' who a full, clear, and exact description soil-engaging members or plow bottoms.

-With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings Figure l is a view in side elevation illustrating an embodiment of my invention, and Flgs. 2, 3,

and 4' are detail views.

1 represents the rear diagonal beam of the truck frame of an engine ang plow structure and to this beam brac ets'2 are secured, the number of such brackets corresponding to the number of plow units to be employed. In the drawing, a single plow unit is shown, b'u't'it will be understood that a plurality of such units will be comprised in the plow structure. All'of said plow units and the adjusting means. therefor, are the same in construction, and hence a, detail description of one ,willeuifice for all. Each plow unit comprises two beam members 3-4 spaced apart and at their rear ends these members receive between them the upper portion of afilow standard 6, said standard beingsecure ;at its lower end to the soilengaging member 7.-- The forwardends of the beam members 3-4 are connected'by a bracket 8, and the latter is provided with forwardly projecting arms 9 having-bosses 10. Sleeves 11-12 are mounted in the bosses 10 and are provided at their outer ends with eccentrics 13 and 14 respectively (each preferably having a slight taper), which enter eccentric boxes 15-16 secured to the side members of the bracket 2. Normally, the eccentrics 13-14 are disposed approximately Specification of Letters Patent. Patented J 11113 23, 1914 Applloation fll'ed September 17, 1913s Sena-1N0. 790,342.

at right angles to each other,-viz., approxithe sleeves and insures close fit of the eccentries in their boxes,,but permits said eccentries to ing adjustments of the beam members as hereinafter described. The inner end portions of the sleeves 11-12 are made angular exteriorly as shown at 20* and to these angular portions of the sleeves, arms 20 having bifurcated upper ends, are secured. Levers 21-22 are pivotally connected at 21, 22 with the bifurcated upper ends of the arms 20 and between said levers, segments 23 are located,-said segments being formed at respective sides of a bracket 24 secured to the truck-frame bracket 2. The levers 21-22 are provided with detents 25 to engage the segments and are normally pressed into such engagement by means of springs 26, which bear at their respective ends against lugs 27 on the levers on the arms 20,

With the construction and arrangement of parts as above described, the sleeves 11-12 and their connection with the bracket 2 on the truck frame, constitute pivotal supports for the forward end of the plow beam, and on which said beam may swing vertically during the normal operation of the plow. By moving the lever 21 in one direc tion or the other, the eccentric 13 with which this lever is connected will be turned in the eccentric box 15, and one side of the bracket 8'with which the beam members are connected will be moved forwardly or back'-' wardly, and thus cause the plow beam, standard and soil-engaging member to be moved laterally for the purpose of pro erly spacing the plow unit from its neigh ors. When the lever 22 is moved, the eccentric 14 will be turned in the eccentric box 16 and one side of the bracket 8 will be raised or lowered and one beam member will .be raised or,lowered relatively to the other, thus effecting an adjustmentof the plow unit to properly level the soil engaging memben Various slight changes might be made in yield sufficiently to enable the shift-,

and lugs 28 the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not Wish to restrict myself to the precise detalls herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. The combination with a truck frame, a truck frame bracket, and a plow, of boxes on the truck frame bracket, eccentrics carried by the plow and mounted in said boxes, and manually operable means connected with each of said eccentrics for operating the same to adjust the plowl 2. The combination with a truck frame and a plow, of boxes disposed opposite to each other and carried by the truck frame, eccentrics carried by the plow and mounted to turn in said boxes and manually operable means for operating said eccentrics.

3. The combination with a frame and a plow, of two boxes carried by the frame, ec-

centrics carried by the plow and mounted in said boxes, said eccentricsbeing normally disposed at approximately right angles to each other, and operating means connected with each eccentric.

4. In a gang plow, the combination with a truck frame, truck frame brackets and plow units, of boxes secured to each truck frame bracket, eccentrics carried by each plow unit and mounted in said boxes and means for operating said eccentrics to adjust -the plow unit.

5. In a gang plow, the combination with a truck frame, a truck frame bracket, and a plow unit, of cam boxes secured to the truck frame bracket, eccentrics carried by the plow and mounted in said boxes, a segment connected with the truck frame bracket, and a lever secured to each eccentric and provided with means to engage said segment.

6. In a gang plow, the combination with a truck frame and a plow, of two eccentric structures connecting the plow with the truck frame and constituting pivotal connections for said plow, and means for independently operating said eccentric structures to effect lateral and leveling adjustments of the plow.

7. In a gang plow, the combination with a truck frame, a bracket secured thereto, and a plow, of a bracket secured to the plow, eccentric connections between respective sides of said bracket and respective members of the adjacent truck frame bracket, means for operating one of said eccentrics to effect lateral adjustment of the plow, and means for operating the other eccentric to effect leveling adjustment of the plow.

8. In a gang plow, the "combination with a truck frame, a bracket secured thereto and a plow,,of a bracket secured to the plow, sleeves mounted in 'said last-mentioned bracket, eccentrics carried by said sleeves, one of said eccentrics normally disposed at an angle with respect'to the other, boxes secured to o posite members of the adjacent truck bracket and receiving said eccentrics, and levers connected with said eccentrics for turning the same to effect lateral and leveling adjustments of the plow unit.

9. In a gang plow, the combination with a truck frame, a truck frame bracket and a plow, of a bracket secured-to the plow, sleeves mounted in saidlast mentioned bracket, eccentrics carried by said sleeves and disposed at an angle to each other,'boxes secured to opposite members of the adjacent truck frame bracket and receiving said eccentrics, pivoted spring-pressed levers connected with said sleeves, segments disposed between said levers and secured to the truck frame bracket, anddeteiifs on said levers to engage the .segments.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
